Roll vs. tile, by hand, with arrows.
You're tracing irregular rooms off A-sheets, dragging seam diagrams in two different tools, drawing pile-direction arrows by hand. Waste factor is a guess. One quarter-turn ashlar pattern adds 8% and nobody told the bid.
Auto seam plan with pile direction.
Every room is gridded, every tile placed, every broadloom seam drawn with LF and pattern offset. Quarter-turn, monolithic, ashlar - pattern locked at the spec, waste reported per room. 0.3% seam waste on the comparable jobs we've shipped.
